Some time ago, I replaced my old IBM Thinkpad with a Dell notebook that has an Intel IPW2200 wireless network card inside. With that, I lost the ability to monitor wireless networks with Kismet.

But as Patrick Olsen describes in "ipw2200 driver install on Fedora Core 4", the latest versions of the IPW2200 driver and Kismet work together just fine. Installation is even easier than described by Patrick - you do not need the kernel source. The only thing to look out for is to first remove old versions of ieee80211 and ipw2200 with the remove-old script from each package, and then compile and install ieee80211 and ipw2200 in that order. Also, the current version of ieee80211 has trouble deleting two directories in /lib/modules, so I manually moved include/config/ieee80211 and drivers/net/wireless/ieee80211 about which it complained out of the way.

On my Dell D800, the source setting for Kismet is ipw2200,dev30359,ipw2200, where dev30359 is the same interface name displayed by iwconfig.
